STARTER FR EXPLOSIVE1ENGINES.

Specification of Letters Patent.

Patent ed Der. 23, 1913.

Application filed January 25, 1912. Serial No. 673,402.

To all om t may concern l Be it known that l9 MARTIN C. BRIGHT, l a citizen of the United Statesr` residing at. Indianapolis. in the county or" Marion and l State of Indiana, have invented certain new and useful Improvements in Starters `t'ol Explosivedilng'ines. of which the following Il a .speci cation. l

This invention relates to improvements in l starters for hydro-carbon engines. and the Il object is to provide means for supplying a i' hydro-carbon explosive mixture when `they engine is at'rest, to that one of a plurality of cylinders of the engine. which, in its l5 .regular running sequence, shouidbe the next cylinder to be lired.

.A further object is to provide a simple f and inexpensive device that can be at-l tachedto a magneto-generator and operated from the spark-contributor shaft of the ltfl ter which is timed with the cycles of the engine, and my enplosive mixture supply: ing device thereby timed with both the emi gine and the magneto.

The object, also, is to provide inea-ns 'for' the independent adjustment of my device to time it with the magneto und engine.

` I accomplish the above objects by the mechanism illustrated in the accompanying Figure l is a vertical section on the line 3&3 of Fig. 2 through the axis or' the dist-ributenshaifl' of the magneto havingr my invention applied thereto. Fig. 2 is an end Fig. ,l showing, saine diagrammatically con# nected up With a pumpv and also `with the cylinders of a four-cylinder engine, and

Fig. 3 is a vertical cross section on the line `bof Fig. l.

Like characters of reference indicate like parts through the several views of the drawing.

1, 2. 3, and 4, are the .respective cylinders of a. four-cylinder gasolene engine. As my device may be used with` an engine having a greater or less number of cylinders it Will be understood that a four-cylinder engine is only shown here by Way of illustration.

5 is a magneto of any usual and suitable type, in which 6 is the armature shaft which is connected bv a worm and gear 7 with the Crankshaft 8 of the engine. Other ap- WONU device having its outer end l2 cast integrally with said cylindrical sides, and having an external flange 13 at .its opposite end byvvhieh the casel is bolted to a vcase extension M which latter is bolted to the magneto. The inner end ot the case 11 is screw-threaded on its inner side to receive an externally screw-threaded circular head 15. The head lxhas a central bore for the passage through it of an extensipn 17 of the distributor-shaft Irompi-isos a cvlindrical case ll preferably IO. lThe shaft-extension 17 has a reduced and screw-threaded inner,y end 16 which screws into a suitable screw-threaded openin;f i-n the end of shaft 10. The shaft-extension i7 is provided with a screw-thread adjacent to the reduced end 16, opposite in direction to the thread on said reduced end, that is. 1.6 being provided with a. right-hand thread then the adjacent portion of shaft extension l? will be provided with a left.- hand thread. Screwinfr upon the threadedend of 17 is a metal bearing-sleeve 18, and between the end ot' shaft l() and the sleeve 18 is a split lock-Washer 19. This provides means for holdingr any desired ,rotary adjustment ef extension 17 with relation to the distrihuter-shaft 10, intiming the valve of my hydro-carbon distributor, hereinafter to be described, with the electric current dismagneto for' The head l2 has aY the ignitiont2 eti l, i Y
